Answer:
The observations are: 6, 8, 9, 15, x, x+
2, 21, 22, 25, 29
The number of observations are 10. Since, the observations are even the median will
be the mean of n/2 and n/2+ observations
median = mean of 10/2and 10+ 2/2
1 observations
median = mean of 5th and 6th observations
median =x+x+2/2
17 = x+1
x= 16
